In summary, to calculate the pressure at the intersection of three centrifugal pumps, you will need to consider the discharge of each pump, the flow rate of each pump, and the pump curves. Without this information, it is not possible to accurately determine the pressure. It is recommended to consult the manufacturer for pump curves and obtain pressure readings at various points in the pipe for a more precise calculation.

Are the pipe discharges from the pumps symmetrical (or similar) to the header (intersection)?

Do you know the flow rate of each pump (or the combination?)

Do you have a pump curve for the pumps? (if not ask the manufacturer)

Do you have any pressure readings the the pipe anywhere?

There is no way to mathematically determine the pressure at a given point in a pump system with just the flow rate. My question about the flow rates was leading toward the next question, do you have the pump curves for the centrifugal pumps. If they are putting out 350 m3/hr, then you need only look at the curves to determine the

Fluid mechanics is the study of how liquids and gases behave and interact with their surroundings. It is a branch of physics that focuses on understanding and analyzing the motion and forces of fluids, such as water, air, and oil.

Pressure in a pipe is the force per unit area that a fluid exerts on the walls of a pipe. It is caused by the weight of the fluid above it and the motion and collisions of molecules within the fluid.

Pressure in a pipe can be calculated using the equation P = F/A, where P is pressure, F is force, and A is the cross-sectional area of the pipe. The force can be calculated using the weight of the fluid and the acceleration due to gravity, while the cross-sectional area can be measured or calculated.

The pressure in a pipe is affected by the density and weight of the fluid, the velocity of the fluid, and the shape and size of the pipe. Other factors such as temperature, viscosity, and external forces can also impact pressure in a pipe.

According to Bernoulli's principle, as the fluid velocity increases, the pressure decreases. This is because the kinetic energy of the fluid increases, causing a decrease in potential energy and pressure. This relationship is known as the Bernoulli effect and is essential in understanding and designing fluid systems.
